Description

PPIases accelerate the folding of proteins. It catalyzes the cis trans isomerization of proline imidic peptide bonds in oligopeptides. Participates in pre mRNA splicing. May play a role in the assembly of the U4/U5/U6 tri snRNP complex. May act as a chaperone. The protein encoded by this gene is a member of the peptidyl prolyl cis trans isomerase (PPIase) family. PPIases catalyze the cis trans isomerization of proline imidic peptide bonds in oligopeptides and accelerate the folding of proteins. This protein is a specific component of the complex that includes pre mRNA processing factors PRPF3, PRPF4, and PRPF18, as well as U4/U5/U6 tri snRNP. This protein has been shown to possess PPIase activity and may act as a protein chaperone that mediates the interactions between different proteins inside the spliceosome.
